A Note on Shrinkage Stresses in Continuous Steel-concrete Composite Bridges

Continuous steel-concrete composite bridges develop longitudinal tensile stresses in their deck slab as a result of differential strains caused by shrinkage. Analytical procedures are described whereby the shrinkage stresses along continuous, non-uniform composite beams can be estimated. The accuracy of these predictions is assessed in relation to the results of a laboratory test on a two-span continuous beam. In addition, existing design recommendations are examined and typical distributions of stresses in medium span bridges are presented. A.E. Long and P. Csagoly
